  2. 03' Vulcan 750... No Idle without choke.

    Carbs and Fuel System
    I bought a 2003 Vulcan 750. The bike had set for an unknown amount of time with gas in it. (the guy said 24 months.. but the tags expired in 2009) I got the bike home shot some brake cleaner up in the carbs and it started right up. I took and emptied the gas tank. put half a bottle of Seafoam...
  3. motor will not rev up when in n./battery not charging

    my 86 vn750 will not rev up in neutral, it idles fine but when i give it a little roll on it sputters and misses. put it in gear and all is well.

    VN750 General Discussion
    Okay so I picked up my vn750 3-4 days ago from a guy about 100 miles away from where I live. Went and got it, drove it home, rode fine. The last 4 days the engine has been "cutting out".. I'll be driving it and all the sudden it will start to lose power. Depending on how badly at the time it is...
  5. Idle problem. RPMs going haywire.

    Carbs and Fuel System
    Ok so I was riding my 86 vn750 a few days ago and realized I was maintaining 40 mph with the throttle closed. I pulled the clutch in and the RPMs jumped to 3 or 4 thousand. I got it home, messed with the idle screw and throttle cables and it didnt help. When I turn the idle screw down eventually...
  6. Fast Idle with warm engine

    Carbs and Fuel System
    Wasn't sure what section this should go under.... Anyway, my 750 runs great, starts right up. When it's cold, I back off the choke, and it idles perfect at 1100. What has been happening intermittently, is once I ride for a while, and the bike is good and warm, when I come to a stop sign, or...
  7. Idle problems

    Carbs and Fuel System
    My bikes been running really rough it just doesnt idle right. it starts up no problem but then you have to keep blipping the trottle or leave the choke open. it also sounds like the bike is starving for gas even when holding the throttle open at a steady rpm, misses while riding, and sometimes...
  8. engine idle problem

    VN750 General Discussion
    My bike's engine doesn't slow back down to idle speed fast enough when I release the throttle, especially when the engine heats up past the second line on the engine temp gauge. would any one know what I'm talking about, what the problem is, & how I or a technician can do to solve this problem...
  9. Hydrocarbon smell in exhaust at idle

    Engine / Exhaust / Cooling
    My 2003 runs well but idles unevenly with an objectionable smell of unburned hydrocarbons. The idle speed is within spec and at less than 11,000 mi the bike is still a baby -- no oil burning and no smoke at all. Switched to Iridium plugs with good results. Never had the carbs off but did have...
